Description

Yoshi's House

The starting level in the game, it changes when the Special World is beaten. The OW graphic is of the Boathouse in 1000 AD, from Chrono Trigger.

Normal Level

A normal level is the default design for levels. The player must traverse these levels in order to unlock the next level. Normal levels resemble yellow ovals on the ground.

Double Exit Level

Double Exit levels are just like normal levels, except that they have a second, secret exit.

Koopaling Castle

Koopaling Castles are the castles at the end of each world. Each Castle houses a different Koopaling. The Castles also usually hold a Red Door, a Dragon Orb, a Secret Exit (Lemmy's Castle and Ludwig's Castle only), and a Boss (Besides the Koopalings). The OW graphic is of the boss stages from Donkey Kong Country 2.

Ghost House

Ghost Houses are special levels filled with Boos. Big Boo will sometimes appear as a boss in Ghost Houses. The OW graphic is of the villages from Romancing SaGa 2.

Fort

Forts are special levels that appear seven times. Forts usually contain multiple Doors and are mazelike. The OW graphic is of the Ancient Library from Final Fantasy V, but with the roof recolored red (it was originally light blue).
